A fusion engine works by combining two or more atomic nuclei to form a heavier nucleus, releasing a large amount of energy in the process. This process is similar to what powers the sun and other stars.
A fusion engine has the potential to provide a nearly limitless source of clean energy, as it produces no greenhouse gases or radioactive waste. It could also potentially reduce our dependence on fossil fuels and help combat climate change.
One of the main challenges in developing a fusion engine is containing and controlling the extremely high temperatures and pressures required for fusion to occur. Another challenge is finding materials that can withstand these extreme conditions and developing a sustainable fusion reaction.
There are several research projects and experiments currently underway to develop a fusion engine, including the International Thermonuclear Experimental Reactor (ITER) in France and the Joint European Torus (JET) in the UK. While progress has been made, a practical and commercially viable fusion engine is still in the early stages of development.
It is difficult to predict an exact timeline for when a fusion engine will be available for use, as it depends on the progress of research and development. Some experts estimate that a practical fusion engine could be available within the next few decades, while others believe it may take longer. However, continued advancements in technology and research bring us closer to achieving this goal.
